Performance history in South Africa

A play called Rob Roy MacGregor Campbell, said to be based on Scott's novel, was performed a number of times in the African Theatre, Cape Town by the amateur company English Theatricals in the years 1823-24 (it is later simply referred to a Rob Roy in the sources). It is most likely that this was the widely known and published Pocock musical version, but it may have been the William Henry Murray version, entitled Rob Roy Macgregor, which had been devised in association with Scott and was performed in Edinburgh in 1818.
